Can we pay too much attention to details? Absolutely. Perfectionists struggle over little things at the cost of something larger they work toward. Charles Garfield, associate professor at the University of California, San Francisco, says that to keep from losing the forest for the trees, we must constantly ask ourselves how the details we're working on fit into the larger picture. If they don't, we should drop them and move on to something else.
Garfield compares this process to his work as a computer scientist at NASA. "The Apollo II moon launch was slightly off-course 90 percent of the time, but a successful landing was still likely because we knew the exact coordinates of our goal. This allowed us to make adjustments as necessary. Knowing where we want to go helps us judge the importance of every task we undertake."
Success is rarely mysterious. We see that by doing little things within our grasp, well, large rewards follow.
